LAWN-ROLLER.

To all whom it may concern Be it known that I, GEORGE E. KA L, a citizenof the United States, resident of Cleveland, county of Guyahoga, andState of Ohio, have invented a new and useful Improvement inLawn-Rollers, of which. the following is a specification, the principleof the invention being herein explained and f the best mode in which Ihave contemplated applying that principle, so as todistinguish it fromother inventions. My invention relates to lawn-rollers and particularlyto lawn-rollers in which the.

heads are eachprovided with a central open-' ing surrounded by anoutwardly extending flange united by welding to theen ds of an embodyingmy invention, the disclosed and with a central opening 6 surrounded byaxle tube extending through such openings. Its object is to provide astructure in which the joint formed by such describedunion will beprotected against abrasion resulting from the frictional action ofcontiguous relatively moving parts.

The said invention consists of means hereinafter fully described andparticularly set forth in the claims.

The annexed drawing and the following description set forth'in detailcertain means means, however, constituting but one of various mechanicalforms in which the principle of the invention may be applied.

In said annexed drawing :Figure 1 represents an end elevation of alawn-roller embodying my invention, showing only a fragmentary portionof the handle. Fig. 2 represents an axial section of the roller showingpart of the handle and the axle-rod in elevation. Fig. 3 represents anaxial section of a fragmentary portion of the roller, upon an enlargedscale, showing the details of construction of the bearing parts of oneof the handle members, and the contiguous parts of the body-portion ordrum of the roller.

The illustrated .device comprises a main portion or drum l, and thehandle 2. Said drum consists of a cylindrical shell 3 provided with twoend heads 4:, 4:. Each headis formed with an outwardly extending flange5 welded to the contiguous end of the shell an outwardly extending shortannular flange 7 welded to the contiguous end 8 of an axle tube orsleeve 9, as shown in Fig. 3, the two together forming an outwardlyside.

extending flange. Extending through said sleeve with itsendextendingconsiderably beyond the ends of said flanges 7, isan axle-rod10.

the washer to snugly fit upon the rod .10.

Surroundingsaid opening 14: is a countersunk portion or depression l5upon its inner The thickness of the washer ismade such that the saiddepression maybe made of a depth such that the said joint may proectllltO said depression, without coming into contact with the washer whilethe inner surface of the latter is engaging the con- Fig. Betweentheroller-bearing and said washer an auxiliary washer 16 may be placed ifdesired, and an outer washer 17 is provided and held on the rod by meansof a Eipecification of Letters Patent. 7 Patented Dec, 15, I Applicationfiled February 16, 1914. Serial NO. 819,078.

The projecting ends of this rod} form journals for roller-bearings 11 ofeach roller-beartiguous surface of the head 4, as shown in i cotter-pin18, thus retaining the rollers 19 of i said roller-bearing.

By means of the above described construc -o 9 tion, it will be seen thatabrasion of the welded jointsformed by the flanges 5 and tube ends 8 isprevented and all wear due to movement of parts, other than the rollersand journals on rod 10, transmitted to the,

washer 13 and the heads 1,-'thus preventing the abrasion of said ,jointand eliminating the danger of leakage which might therefrom.

result Having fully described my invention,

.what I claim and desire to secure by Letters Patent is 1. In alawn-roller, the combination of a roller-head having a central,outwardly:

projecting flange; a journal-member coaxial with said flange; abearing-member mounted upon said journal-member; and a washer interposedbetween said head and said bearing-member and detached from said head;said washer being formed with an annular groove upon its inner face;said flange projecting into said groove.

2. In a lawn-roller, the combinatlon ofa roller-head having a central,outwardly-' projecting flange; a journal-member's coaxial with saidflange; a bearing-member mounted upon said journal-member; and aseparating member interposed between said bearing-member and headadapted to engage the latter while out of contact with the end of saidflange.

3. In a lawn-roller, the combination of a roller-head having a centralopening surrounded by an outwardly projecting flange an axle projectingoutwardly through said opening and beyond said flange; a bearingmembermounted upon the outwardly projeeting portion of said axle member; and awasher interposed between said bearingmember and flange; said washerformed with a central opening through which said said groovebeing suchthat the washer may 20 engage the-adjacent surface of said head whileout of contact with the end of said flange.

Signed by me, this 12th day of February,
